- You skip seed phrase backups but rely on exchange access rules.
- Withdrawals can require checks or pause during outages.
- Crypto balances are not FDIC or SIPC insured.
The tradeoffs of exchange custody are convenience and recovery help against counterparty risk and platform control. The exchange holds the private keys tied to your account, so you trade from a recoverable login but follow its rules for access and withdrawals.
How does exchange custody work?
With exchange custody, the company controls the private keys for your crypto. You sign in with a username and password, and the platform can help you regain access if you forget them. You skip seed phrase backups, but the exchange sets the rules for logins and withdrawals.
What can go wrong with exchange custody?
Most exchange custody risks come from the platform, not from your own key handling. Its financial health and security matter.
- Withdrawals can require identity checks, waiting periods, or be suspended during outages.
- If the exchange fails or freezes, you may become a general creditor.
- If the exchange is hacked, coins in its custody can be stolen.
- Crypto balances are not FDIC or SIPC insured; fiat cash may have limited FDIC coverage through partner banks.
How is it different from self-custody?
Self-custody means you hold the private keys and recovery phrase. You gain direct control and do not depend on exchange withdrawal rules, but you bear the loss risk if you lose your keys or share your seed phrase.
How do you keep exchange access safe?
Your login and withdrawal settings are the gate to your funds. A weak password or lost two-factor device can lock you out.
